Hacking Some of my older R4 saves don't work

[Chihaya]

I've had a DSTT for about 6 months and it's been working great, except I've never been able to get some of my older save games from the time I had an R4 to work. Some did work fine, but namely, I could never get Castlevania Dawn of Sorrow and Etrian Odyssey to recognize old save games, they just say that there are no older game saves present when I try to load them in-game even though the corresponding .SAV files are there.

This is especially grieving me in the case of EO, I hope I haven't lost all those hours...

Aren't the R4 and DSTT using the same file format for saves? What could be the beef?

Try renaming the .SAV to .sav (minimize letters)

Not working

damn I hope my EO save wasn't overwritten in some way when it was first opened by the DSTT OS
